Abstract

Eighteen species and one subspecies are recorded, of which five species and one subspecies are known only from caves. It is believed that these latter species were originally epigean species which entered each cave in which they are known independently and then became extinct on the surface, rather than that each originated in a single cave and migrated through subterranean passages to reach its present range.
